Products description

Britax Römer presents the Kidfix III M, a new car seat in the Kidfix range. The child seat is developed and produced in Germany. Made in Germany!
Many children fall asleep in the car - the head often tilts forward which, especially on longer trips, leads to neck pain and general discomfort. In addition, many children complain about uncomfortable seats in the back and sitting area.

The Kidfix III M offers a lot of comfort with its very high quality and well-padded seat and back. The long seat with soft support provides a particularly pleasant and relaxed leg posture. The large side protection in the head area provides extra grip and reduces the risk of the head tilting forward. The wide backrest is v-shaped and offers support for small and large children.
On the back, the backrest can be easily pulled out and adjusted and thus optimally adapted to the height of the child.

An absolute premium product that we personally can recommend.

The attachment is made via the Isofix system and the three-point belt of the car.

High back protection

Our child seats with backrest protect your child in three ways: the seat protects your child from head to hip, especially in the event of a side impact. At the same time, the upper and lower belt guides ensure that the seat belt is in place and the padded headrest provides safety and comfort for your child's head and neck.

Removable cover

Sometimes things get pretty chaotic in the car. Drinks are spilled easily or your child might get sick from the movements of the car . Therefore, Britax Römer has developed a seat cover that is easy to remove and machine washable. So you can clean the seat easily and quickly.

Ergonomically optimized seat

The seat of the KIDFIX III is about 20% larger than similar models. That means maximum comfort - even for larger children. On longer journeys, the optimized shape and the extra soft padding also ensure a comfortable and ergonomically optimal sitting position.


The SecureGuard helps to protect your child's sensitive abdomen - with an extra attachment point for the adult's 3-point seat belt. By optimally positioning the lap belt over your child's pelvic bones, the SecureGuard reduces the forces of a frontal impact by up to 35% *, while giving your child sufficient freedom of movement while being in the car.

* Internal Britax testing with a Q6 dummy that is the same size and weight as an average 6-year-old child.

Side Impact Protection - SICT

In the event of a side impact, your child is optimally protected thanks to Side Impact Protection Technology (SICT). On one hand the forces that your child is exposed to in the event of a side impact are diverted away from them, and on the other hand they are weakened before they reach your child. To ensure that your child is optimally protected, you should use the SICT technology on the side which is facing the door.

Easy adjustable, ergonomic headrest

Our headrest was specially developed for older children, who are strapped in the child seat with the 3-point safety belt. The headrest can be easily adjusted to the right position - just above the child's shoulders - with one hand, even when your child is sitting in the seat. And because the headrest is ergonomic, it supports your child's head when it falls asleep.

Easy-to-adjust V-shaped backrest

The v-shaped backrest has been designed to give your child more space on the back and shoulders as they grow. As a result, your child is always optimally supported. In addition, the backrest of the child seat adapts automatically - aligning it with the angle of the vehicle seat. So that it fits better and your child sits in a more comfortable position.

This child seat must be installed in your vehicle with the vehicle's 3-point harness and ISOFIX anchorage points.

Please see the product list or our FIT FINDER® product page to see if the child car seat is compatible with your car.

• With belt
This child seat can be installed with the vehicle's 3-point harness. This is convenient if you install the child seat in different cars that may not all have ISOFIX anchorage points. The belt guides on the car seat help you to install the child seat correctly. In your vehicle manual you will find the vehicle seat positions suitable for your car.
As a trained specialist we will gladly build the child seat on site.
